Description

Technical Field

[0001] This utility model relates to a heat dissipation cabinet, and more particularly to a double-door liquid-cooled heat dissipation cabinet that can improve cooling efficiency and avoid the problem of insufficient heat dissipation of single-door liquid cooling by means of heat exchange units corresponding to the front and back of the double doors. Background Technology

[0002] With the increasing demands for artificial intelligence training, big data analysis, cloud computing, and high-performance computing, data center servers consume a significant amount of power. Traditional air cooling is no longer sufficient to meet the cooling needs of these high-power servers because it is inefficient and relies on numerous fans and air conditioning units, resulting in high energy consumption. Therefore, liquid cooling is gradually replacing traditional air cooling, as it can more efficiently remove heat from the server's heat-generating components and extend the equipment's lifespan. Currently, most liquid-cooled server racks are single-door configurations or require external CDUs (Cooling Distribution Units), which have limitations in heat dissipation efficiency and complex installation.

[0003] Please refer to Taiwan Patent No. TWM610359, "Gas-Liquid Water-Cooled Server Rack," which mainly includes a rack heat exchanger, cooling fluid piping assembly, and liquid cooling lines connecting to the heat exchange chamber inside the server. It achieves heat exchange through first and second cooling fluid input and output piping, and requires a fan module to facilitate gas-liquid heat exchange. However, this design has at least the following drawbacks:

[0004] 1. Liquid-cooled heat exchangers are located on a single side, resulting in limited heat dissipation efficiency, which cannot effectively support high-density server clusters.

[0005] 2. The structure of this case still depends on airflow and cannot operate stably for a long time in an environment without air conditioning.

[0006] 3. With only a single heat exchanger, it is impossible to dissipate heat from both the front and rear doors simultaneously, resulting in insufficient heat dissipation uniformity.

[0007] 4. Lacking an independent closed-loop design, its operation requires close connection with external cooling equipment, resulting in insufficient system flexibility. Utility Model Content

[0008] In view of the above, the purpose of this utility model is to provide a double-door liquid-cooled heat dissipation cabinet that can improve cooling efficiency and avoid the problem of insufficient liquid cooling heat dissipation of a single door by means of heat exchange units corresponding to the front and rear of the double doors.

[0009] To achieve the above objectives, this utility model provides a double-door liquid-cooled heat dissipation cabinet, characterized in that it comprises:

[0010] A cabinet has an internal storage space for housing a heat source device. The cabinet has two doors located at openings on the front and rear sides of the cabinet. Each door contains at least one heat exchange unit for cooling and dissipating heat from the heat source device using coolant.

[0011] A transmission unit is configured in the cabinet. The transmission unit includes an inlet pipe and an outlet pipe. The inlet pipe is used to input coolant into the transmission unit, and the outlet pipe is connected to the heat exchange unit and used to transport the coolant in the transmission unit to the heat exchange unit.

[0012] A return water pipe connects to the heat exchange unit to receive the temperature-rising coolant output after heat exchange by the heat exchange unit.

[0013] A condensing unit is connected to the return water pipe via an input terminal and to the inlet water pipe via an output terminal. The condensing unit returns the temperature-rising coolant output from the return water pipe to the condensing unit, which cools the temperature-rising coolant and outputs it to the inlet water pipe.

[0014] The aforementioned dual-door liquid-cooled heat dissipation cabinet includes a heat exchange unit comprising a plurality of tubes, having an input section for inputting coolant and an output section for outputting the cooled coolant after heat exchange. The cabinet is also equipped with a piping unit, wherein the outlet pipe is connected to the input section via an inlet branch valve and several inlet branch pipes, and the return pipe is connected to the output section via a return branch valve and several return branch pipes.

[0015] The aforementioned dual-door liquid-cooled heat dissipation cabinet includes at least one fan in each of the two doors for guiding ambient air into and out of the cabinet. The cabinet is also equipped with an electronic control unit connected to a plurality of sensors. These sensors detect the operation of the fans and the temperature and flow rate of the coolant. The electronic control unit is connected to an artificial intelligence platform, which adjusts the coolant temperature, flow rate, and fan airflow based on the real-time data monitored by the sensors.

[0016] The aforementioned double-door liquid-cooled heat dissipation cabinet, wherein each of the two doors is equipped with a filter unit corresponding to the heat exchange unit.

[0017] The aforementioned dual-door liquid-cooled heat dissipation cabinet, wherein the two doors are pivotally connected to the cabinet by at least one pivoting element.

[0018] The aforementioned double-door liquid-cooled heat dissipation cabinet, wherein the water inlet pipe is connected to a water tank, the water tank contains coolant and is connected to a pump, the pump is used to draw coolant from the water tank and output it through the water outlet pipe.

[0019] This invention utilizes heat exchange units corresponding to the front and rear of the double doors to improve cooling efficiency and avoid the problem of insufficient heat dissipation from single-door liquid cooling. Even in environments without air conditioning, it can provide stable heat dissipation for high-power-density heat source equipment (such as IT equipment) in the cabinet around the clock. This invention has high heat dissipation efficiency, reduces energy consumption, and improves equipment operational reliability. Attached Figure Description

[0031] like Figures 1 to 9As shown, this utility model provides a double-door liquid-cooled heat dissipation cabinet, which includes a cabinet 10, a transmission unit 20, a return water pipe 30, and a condensation unit 40, which will be described in detail below.

[0032] The cabinet 10 has an internal storage space for housing heat source equipment. The cabinet 10 has two doors 50 and 60, which are located at the openings on the front and rear sides of the cabinet 10. The two doors 50 and 60 contain at least one heat exchange unit 51 and 61 for cooling and dissipating heat from the heat source equipment using coolant.

[0033] The transmission unit 20 is disposed in the cabinet 10. The transmission unit 20 includes an inlet pipe 21 and an outlet pipe 22. The inlet pipe 21 is used to input coolant into the transmission unit 20, and the outlet pipe 22 is connected to the heat exchange units 51 and 61 and is used to transport the coolant in the transmission unit 20 to the heat exchange units 51 and 61.

[0034] The return water pipe 30 connects to the heat exchange units 51 and 61 and is used to receive the temperature rise coolant output by the heat exchange units 51 and 61 after heat exchange.

[0035] The condensing unit 40 is connected to the return water pipe 30 via an input end and to the inlet water pipe via an output end, so as to return the temperature rise coolant output from the return water pipe 30 to the condensing unit 40. The condensing unit 40 can cool and reduce the temperature rise coolant and output it to the inlet water pipe 21.

[0036] In one embodiment of the present invention, the heat exchange units 51 and 61 include a plurality of tubes and have an input section 52 and 62 for inputting coolant and an output section 53 and 63 for outputting the cooled coolant after heat exchange. The cabinet 10 is further configured with a piping unit 70. The piping unit 70 is constructed such that the outlet pipe 22 is connected to the input section 52 and 62 through an inlet branch valve 71 and several inlet branch pipes 72, and the return pipe 30 is connected to the output section 53 and 63 through a return branch valve 73 and several return branch pipes 74.

[0037] In one embodiment of the present invention, the two doors 50 and 60 include at least one fan 54 and 64 for guiding ambient air into and out of the cabinet 10. The cabinet 10 is further configured with an electronic control unit 80, which is connected to a plurality of sensors to sense the operation of the fans 54 and 64 as well as the temperature and flow rate of the coolant. The electronic control unit 80 is connected to an artificial intelligence platform, which adjusts the coolant temperature, flow rate and air volume of the fans 54 and 64 based on the real-time data monitored by the sensors.

[0038] In one embodiment of the present invention, the two doors 50 and 60 are provided with a filter unit 55 and 65 corresponding to the heat exchange unit 51 and 61.

[0039] In one embodiment of the present invention, the two doors 50 and 60 are pivotally connected to the cabinet 10 by at least one pivoting element 56 and 66.

[0040] In one embodiment of the present invention, the inlet pipe 21 is connected to a water tank 23, the water tank 23 contains coolant and is connected to a pump 24, the pump 24 is used to draw coolant from the water tank 23 and output it through the outlet pipe 22.

[0041] The above description is a preferred embodiment of this utility model. The features and effects of this utility model will then be described below:

[0042] like Figure 10 As shown, when the present invention is used in an environment without air conditioning, the air intake temperature of the front door 50 is equal to the ambient temperature, such as 32°C. After the air enters through the front door 50, it will first cool down by 3 to 5 degrees, such as to 27°C. Then, the air will absorb heat from the heat source equipment in the cabinet 10 and rise again, such as to 37°C. Then, the rear door 60 will also cool down the hot air temperature by 3 to 5 degrees, such as to 32°C. That is, the air intake temperature and the air outlet temperature will be equal to the ambient temperature. The coolant of the cabinet 10 that has risen in temperature flows back to the condenser unit 40 for cooling and then circulates back to the cabinet 10. This meets the requirements of the present invention for 24-hour uninterrupted operation, continuous use, and energy-saving heat dissipation.

[0043] This invention improves cooling efficiency and avoids the problem of insufficient liquid cooling in a single door by using heat exchange units corresponding to the front and back of the double doors. Even in environments without air conditioning, it can provide stable heat dissipation for high-power-density heat source equipment (such as IT equipment) in the cabinet 10 around the clock. This invention has high heat dissipation efficiency, reduces energy consumption, and improves equipment operation reliability.
